Question

What is spermiogenesis and spermiation?

Answer 1

Spermiogenesis:

1. Spermiogenesis is the process of transforming haploid round spermatids into streamlined spermatozoa.
2. The streamlined spermatozoa formed is capable of motility.
3. The process starts when the spermatocytes have completed their two meiotic divisions.

Spermiation:

1. Spermiation is the process of release of mature spermatozoa from the Sertoli cells of the seminiferous tubules.
2. The mature spermatozoa are released into the lumen of seminiferous tubules.
3. This process occurs under the influence of physiological and hormonal factors.
